*4.5. DSC Measurements*

A DSC214 Polyma Differential Scanning Calorimeter (NETZSCH manufacturer, Selb, Germany) was used to study the thermal behaviour of the obtained TO@NZ hybrid and of the pure NZ nanostructures. Quantity 1.2–3.3 mg of samples was heated from 50 ◦C to 300 ◦C, under nitrogen atmosphere, and an increasing temperature rate of 10 ◦C/min.
